To all whom it may concern:

Be it known that I, ll'lANUEL'PAZOS, a subject of the Ring of Spain, residing at Ge-' rona street 37, Barcelona, Spain, have inventedcertain new and useful Improvements in Exp]osion-Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to inane and use the provide novel means for actuating th valves and other auxiliary devices so arranged that the valvesand actuating means thereto are readily removed from the rest ofblthe engine and all the parts easily acces- S1 e.

' In the accompanying drawings, represent- 7 ing an embodiment of my invention, Figure 1 1s a side elevation, partly in section, or my improved engine. Fig. 2 is a horizontal section in line II-I.l of Fig. 1, Figs. 3, l and 5 are views of the rotary valves in several positions, partly in section, Fig. 6 is a perspective of a rotary valve, parts being broken a\ 'ay, Fig. 7 is a perspective of same, partsbcing' proken away along lines VIII- VIII and VIIVII of Fig. (3, Fig. 8 is a longitudinal section through the valve, in plane of lines'VIII-VIII of Fig. 6, Fig. 9 is a diagrammatic view of a valvetaken along lines 9-9 of Fig. 7, in direction of arrows, and Fig. 1G is asimilar view along lines 10-l0 01 Fig. 7, in direction of arrows.

Each rotary valve controls twoicylin-nv 'ders of-the engine; in Fig. litwo rotary -l' cycle engine. I

l, .2, 3 and l represent the 4 cylinders: cylinders l and Bare controlled by rotary valve 5, and cylinders 3 and 4 by rotary valve 6, the. valves located with respect to the cyliudcrs as shown in Fig. being symmetrically between them and to one side. The valve communicates with the cylinders through suitable openings in the side of the cylinder,

the valves is the cylindrical part 9, which is divided into 2 chambers 11 and 12 by partition l0; said partition is provided with a hole 53 for reception of the member 14 on which the valve is mounted.

Radiating outwardly and longitudinally from the cylindrical part 9 are 'l" partitions 7), p 7;". and 2, which alone would form 4. longitudinal chambers just outside the cylinder 9. The partition 10, howevcr,which is at right angles to said radial partitions, is eriitended across two opposite chambers, forming 5% small chambers, namely A'and C on one side and A and C on the other; the other two large chambers. ll and D, extend the whole length of the alve. Chamher A communicates with the longitudinal chamber D through the opening cl, cut through the radial partition. This chamber further communicates with the cylinder 1, by means of a port a, cut through the extcrior wall of the'valve, registering with the opening 39 in the side of the cylinder 1. Longitudinal chamber 8 conniiunicatcs with chamber 11 by means. of the opening (4. and

with the cylinder 1 by the port 1), cut

through the exterior wall of the valve, rcgisteriine with the opening 35). ()n the other side of the valve, analogous ports a? and (l are provided for communication with the cylinder. Chamber A communicates with longitudinal chamber B through the opening 1). Chamber D communicates with chamber 12 by the opening The"valvc is inclosed within a casing 38.

The size of the various openings shown may be varied to suitpractical working conditions, the drawings showing merely the structure and relationship between the various parts.

Chambccll of the valve'lcads directly to the exhaust PS, \vhilc chamber lilon the other side, is connected directly toi'hcchiurgo intake pipe 36 con'ncclcil lo carhurctrr "3. For the olhcr valve. (3, thc right hand sid of the \'2ll\'(! ('ulHl1HHll(:lt0H with the iohz pipe 27 from tho-carlm'rctcr, and the olhvr side with the exhaust 29. The strum; of the valves are precisely similar.

. The valve operates as follows (see Figs. 9 and In the position shown in Fig. 9,

the suction from the cylinder creates a par-' tial vacuum in chamber A, which acts, through opening cl, to create a partial vacuum in chamber D; this sucks a charge from chamber 12, which passes through opening e along chamber D, through opening (1, into chamber A, through port a, and thence into the cylinder.

Simultaneously with theabove, cylinder 2 is exhausting, the path of the gases being as follows: port a, chamber A opening 6 exhaust pipe 23.

" at explosion.

In Fig. 2, the cylinders 1, 2, 3 and 4 are respectively at suction, exhaust, compression and explosion; in Fig. 3, at compression, suction explosion and exhaust; in Fig. 4, at explosion, compression, exhaust and suction; in Fig. 5, at exhaust, explosion, suction and compression.

The valves are mounted on shafts 14-, which terminate in heads 37 engaging with sockets 40 carried at opposite ends of shaft 15. It is evident that rotary motion of the shaft 15 will rotate the valves 5 and 6, and that the head 37 is readily disengaged from the socket 40. The whole valve is then readily removable, upon detaching the upper half of'the casing 38. The shaft 15, through the pulley 16 mounted thereon, and

the shaft 20, through the pulley 19 mounted thereon, are operated by a belt 17 that passes over said pulleys and that receives its power from the pulley 18 mounted on the shaft 24. Shaft 24, carrying pulley 23, is operated by a belt 30; belt 30 is operated by the pulley 33, that is clamped between the disks 31 and 32. The crank shaft 34 of the engine is made in two sections, that terminate in disks 31 and 32, clamped together by bolts 31. At opposite ends of shaft 20 are heads similar to those on shaft 15, that'cngage with the operating shafts of'a circulating pump 21 and magneto 22.

The transmission mechanism is all mount- I ed in the casing 35, which is secured to the the valve, pump and magneto operating means in a readily removable casing, all result in an improved and desirable engine.

I claim 1. A rotary valve for 4 cycle engines, adapted to control two cylinders thereof, comprising two central chambers connected to the charge forming means and exhaust, respectively, an outer member and radii" transverse partitions carrying suitable passages for controlling the paths of the gases through the valves and cylinders.

2. A rotary valve for 4 cycle engines, adapted to control two cylinders thereof, comprising two central chambers, connected to the charge forming means and exhaust, respectively longitudinal partitions radiating therefrom, a transverse partition, and an outer member carrying ports for registering with the cylinder ports, said members carrying openings at suitable points for controlling the path of the gases. r 9,0 3. A rotary valve for four-cycle engines, adapted to control two cylinders thereof, comprising a central member forming two chambers connected to the charge forming means and exhaust respectively, an outer member shaped like two truncated cones, vanes radiating from said central member to the outer member, a transverse artition, the outer member carrying ports adapted toregister with ports in the cylinders and the inner members provided with openings to permit suitable passage of gas.

4. A rotary valve for four-cycle engines, adapted to control two cylinders thereof, comprising two central chambers, connected respectively to the charge forming'means and exhaust, two longitudinal adjacent outlying chambers opening. into said central, chambers, vanes radiatlng from said cen-. tral chamberser transverse partition form-J10 ing smaller chambers, and an outer member carrying inlet and exhaust ports, said vanes and said smaller chambers carrying openings at suitable points.

In testimony whereof, I aflix my signature, in presence of two witnesses.
